FRACO PROVIDES STABILITY
The Guggenheim Building in Rochester, Minn., is one of the outstanding features of a city center steeped in the highest traditions of architecture and design. Part of the Mayo Clinic's portfolio, it was recently found to be in need of a facelift.
Tom Fee, project manager for Minnesota-based Building Restoration Corp., one of the foremost restoration specialists in the Twin Cities area, explained the process.
"The support steel that holds the stone cladding in place required replacement," Fee says. "To achieve this, we had to remove around 200 stone panels weighing between 1,200 and 2,440 pounds each. Our personnel needed a stable working platform that could access 100 percent of the profile of the façade so we could achieve high productivity. Working with Mastclimbers LLC, we developed a U-shaped, twin-mast platform that enveloped the full façade."
The platform, a Fraco ACTS Electric, was designed in conjunction with the manufacturer, according to Kevin O'Shea, safety and training manager with Atlanta-based specialist Mastclimbers LLC.
"Fraco worked closely with us to design a tailormade solution which, since its introduction to the project, has revolutionised the task," says O'Shea. "The productivity benefits are huge. Operationally, the task is infinitely easier with mast climbers than any other form of access."
The training requirement consisted of taking experienced construction tradespeople and introducing them to new technology. "You won't get them on any other type of access now," says Fee. IMAS

333 Omegaseal Water Repellent / Anti-Graffitant
This is a split face block sealer with heavy duty solids. Apply year-round at 20°F and above. This series of water repellents provides hydrophobic protection to masonry surfaces through the formation of a semi-permeable membrane. Its flexible membrane remains intact through thermal movement of the masonry, rejects water in the solid state and allows for moisture vapor transmission. The unique blend of silicone polymers provides maximum resistance to destruction from ultraviolet light and acid rain.
300-C Water-Base Siloxane Concentrate Water Repellent
This product is a VOC compliant, water dilutable, penetrating, breathable, microemulsion concentrated alkoyxy siloxane material, specially formulated for use on precast and site cast concrete, clay and concrete masonry, sandstone and stucco surfaces where surface darkening is unacceptable. The product reduces bonding of airborne dit and hydrocarbons, and water damage caused by freeze/thaw cycles is reduced as well. It provides protection against efflorescence and exhibits excellent resistance to ultraviolet rays and chlorine ions. Exceeds requirements of NCHRP 244, meets SSW 110C Federal Specification and ASTM E514.
303-S Siloxseal Siloxane Water Repellent
Diedrich 303-S Series Products are formulated to protect against the intrusion of moisture that causes efflorescence, leaching, mildew, atmospheric staining and freeze/thaw spalling. The 303-S Series has an excellent resistance to the detrimental effects of acid rain and carbon buildups, 303-5 products are ideal for applications to concrete flat work, parking ramps, stadiums and vertical concrete surfaces because the migration of chloride ions through the cement is reduced, thus reducing the corrosion and deterioration of rebars in reinforced concrete.
